OBJECTIVES: We recently developed a novel minimally invasive surgical approach that combines extracorporeal membrane oxygenation and CentriMag ventricular assist device (Ec-VAD) for the treatment of cardiogenic shock as a short-term circulatory support. We compared the outcomes of this new approach to conventional CentriMag biventricular assist device (BiVAD) support through a median sternotomy. METHODS: Between July 2015 and August 2016, 22 patients were implanted with CentriMag Ec-VAD and 90 patients were implanted with conventional CentriMag BiVAD...

Short-term mechanical circulatory support (MCS) is increasingly used as a bridge to decision in patients with refractory cardiogenic shock. Subsequently, these patients might be bridged to durable MCS either as a bridge to candidacy/transplantation, or as destination therapy. The aim of this study was to review support duration and clinical outcome of short-term MCS in cardiogenic shock, and to analyse application of this technology as a bridge to long-term cardiac support (left ventricular assist device, LVAD) from 2006 till June 2016...

For patients in cardiogenic shock, several devices can serve as a "bridge," ie, provide circulatory support and allow the patient to live long enough to recover or to receive a heart transplant or a long-term device. Options include an intra-aortic balloon pump, TandemHeart, Impella, extracorporeal membrane oxygenation (ECMO), and CentriMag. Which device to use depends on individual patient needs, local expertise, and anatomic and physiologic considerations.

BACKGROUND: Conventional extracorporeal membrane oxygenation (ECMO) is cumbersome and is associated with high morbidity and mortality. We are currently developing the Pittsburgh Ambulatory Assist Lung (PAAL), which is designed to allow for ambulation of lung failure patients during bridge to transplant or recovery. In this study, we investigated the in vitro and acute in vivo performance of the PAAL. METHODS: The PAAL features a 1.75-inch-diameter, cylindrical, hollow-fiber membrane (HFM) bundle of stacked sheets, with a surface area of 0...

Nowadays, sacrificing animals to develop medical devices and receive regulatory approval has become more common, which increases ethical concerns. Although in vivo tests are necessary for development and evaluation of new devices, nonetheless, with appropriate in vitro setups and mathematical models, a part of the validation process can be performed using these models to reduce the number of sacrificed animals. The main aim of this study is to present a mathematical model simulating the hydrodynamic function of a rotary blood pump (RBP) in a pulsatile in vitro flow environment...

With more than 60 years of continuous development and improvement, a variety of temporary mechanical circulatory support (MCS) devices and implantation strategies exist, each with unique advantages and disadvantages. A thorough understanding of each available device is essential for optimizing patient outcomes in a fiscally responsible manner. In this state of the art review we examine the entire range of commonly available peripheral and centrally cannulated temporary MCS devices, including intra-aortic balloon pumps, the Impella (Abiomed, Danvers, MA) family of microaxial pumps, the TandemHeart (CardiacAssist Inc, Pittsburg, PA) pump and percutaneous cannulas, centrally cannulated centrifugal pumps such as the CentriMag (Thoratec Corp, Pleasanton, CA/St Jude Medical, St Paul, MN/Abbott Laboratories, Abbott Park, IL) and Rotaflow (Maquet Holding BV & Co KG, Rastatt Germany), and extracorporeal membrane oxygenation...

Bi-ventricular (Bi-V) mechanical circulatory support is commonly used as a bridge to cardiac transplant. However, the optimal strategy is unknown. We examined the outcomes, as well as the costs in the use of Bi-V support as a bridge to cardiac transplant. From 2001 to 2014, three different Bi-V support strategies were utilized: 1) Para-corporeal ventricular assist device (PVAD-2001-2006), 2) Heartmate II left ventricular assist device in conjunction with a temporary CentriMag right ventricular assist device (HMII + CMAG-2006-2012), and the total artificial heart (TAH-2012-2014)...

The CentriMag, an extracorporeal short-term ventricular assist device designed for treatment of patients with acute cardiogenic shock, is Conformité Européenne-marked in Europe for use up to 30 days. Extended use beyond the licensed period is not uncommon, however. We have developed a skirted cannula technique for apical cannulation in implantation of the Centrimag. This technique allows easy positioning of the cannula and excellent hemostasis. It also offers secure fixation of the cannula so that patients can ambulate and attend rehabilitation programs should extended use be anticipated...

PURPOSE: Low cardiac output syndrome is associated with significant mortality. In patients with refractory low cardiac output left ventricular assist devices (VAD) are used to re-establish cardiac output and to prevent death. However, long-term LVAD implantation in these is complicated by a high rate of right heart failure and mortality. Therefore, our strategy is to implant a short-term VAD (left or biventricular) as a bridge to decission. METHODS: We retrospectively analysed data from 66 patients who received a short-term LVAD support prior to implantation of a long-term LVAD or HTx between 2003 and 2014...

REVIEW
Areo Saffarzadeh, Pramod Bonde
Temporary mechanical circulatory support (MCS) refers to a group of devices generally used for less than 30 days to maintain adequate organ perfusion by compensating for a failure of the pumping mechanism of the heart. The increased availability and rapid adoption of new temporary MCS strategies necessitate physicians to become familiar with devices placed both percutaneously and via median sternotomy. This review will examine the different options for commonly used temporary MCS devices including intra-aortic balloon pumps (IABPs), veno-arterial-extracorporeal membrane oxygenation (VA-ECMO), TandemHeart(®) (CardiacAssist, Pittsburg, PA, USA) Impella(®) and BVS 5000(®) (both Abiomed Inc...

Patients supported with extracorporeal membrane oxygenation (ECMO) or short-term centrifugal ventricular assist devices (VADs) are at risk for potential elevation of plasma-free hemoglobin (pfHb) during treatment. The use of pfHb testing allows detection of subclinical events with avoidance of propagating injury. Among 146 patients undergoing ECMO and VAD from 2009 to 2014, five patients experienced rapid increases in pfHb levels over 100 mg/dL. These patients were supported with CardioHelp, Centrimag, or Pedimag centrifugal pumps...

Extracorporeal membrane oxygenation (ECMO) is indicated when conventional measures fail to support a patient during cardiac or respiratory failure. Due to the complicated nature of ECMO, patients often require transport to a tertiary care center. This study retrospectively compared the performance of the Cardiohelp™ (Maquet) life support system with a previously used ECMO circuit when transporting adult patients on venoarterial ECMO between facilities. Two ECMO circuits were compared for performance: 1) the Cardiohelp™ (Maquet) life support system and 2) the "standard" circuit consisting of a Thoratec CentriMag centrifugal pump, Maquet Quadrox-D oxygenator, and a Terumo CDI-500 in-line blood gas analyzer...

Continuous-flow ventricular assist devices (CVADs) are associated with a significant complication profile that includes thrombosis of the ascending aorta and aortic valve, thromboembolism, and stroke. Despite an increasing number of reports of thromboembolic complications related to CVADs, there is little in the literature to guide their management. This report describes successful management strategies used during two cases of thrombosis of the ascending aorta during biventricular CentriMag (Levitronix LLC, Waltham, MA) support, including using pre-existing cannulas to initiate cardiopulmonary bypass...

Use of extracorporeal membrane oxygenation (ECMO) for severe cardiopulmonary failure has increased because of improved outcomes. A specially designed ECMO transport system allows for safe transport of patients over long distances. We report a 28-year-old pregnant woman (26 weeks gestation) with acute respiratory distress syndrome in whom ECMO support was necessary for survival, and she was transported to another facility 1,155 km away with the aid of the portable ECMO system. Transport was uneventful, and the patient's condition remained stable...

Because of the complexities associated with anticoagulation in temporary percutaneous ventricular assist device (pVAD) recipients, a lack of standardization exists in their management. This retrospective analysis evaluates current anticoagulation practices at a single center with the aim of identifying an optimal anticoagulation strategy and protocol. Patients were divided into two cohorts based on pVAD implanted (CentriMag (Thoratec; Pleasanton, CA) / TandemHeart (CardiacAssist; Pittsburgh, PA) or Impella (Abiomed, Danvers, MA)), with each group individually analyzed for bleeding and thrombotic complications...
